Problem with Samsung and hands free speaker

[NE5]

Hello. I used to have a samsung j5 mobile which I used in the car with a plantronic speaker for incoming calls. It was perfect but I have changed my phone and now have a samsung a20e.

The speaker works properly with audio phone calls but the volume of the ringtone blows my head off.

If I turn the volume down on the plantronic I can't hear the caller and if I turn the ringtone down on the phone then that is too quiet for normal use.

Any ideas please ??

Understood...but how does it differentiate between someone ringing on the phone only and ringing when you're in the car with the speaker turned on.

For info I use my own ringtones for a couple of people so I know who is ringing but the volume is the same for all.of them.
